This is often most apparent at the end of summer when school is about to start again, but it can occur yearround. Where does the stress and anxiety come from? Teachers A good experience with a caring teacher can cause a lasting impression on a child's life-so can a bad experience. While most teachers do their best to provide students with a positive educational experience, some students are better suited for certain teaching styles and classroom types than others. If there's a mismatch (不协调) between student and teacher, a child can form lasting negative feelings about school or his own abilities. Friends Friends can also be a source of stress. Concerns about not having enough friends, not being in the same class as friends, not being able to keep up with friends in one particular area or another, and interpersonal conflicts are a few of the very common ways kids can be stressed by their social lives at school. Dealing with these issues alone can cause anxiety in even the most confident kids. Bullies (欺凌弱小者) Things have changed in the world of bullies since I was a kid.The good news is that teachers and parents are paying more attention. Many schools now have antibullying programs and policies. Though bullying does still happen, help is generally more easily accessible than before. The bad news is that bullying has gone hightech. Many students use the Internet, cell phones and other media devices to bully other students, and this type of bullying often gets very aggressive. One reason is that bullies can be anonymous (匿名的) and enlist other bullies to make their targets miserable.Another reason is that they don’t have to face their targets. So it’s easier to get rid of any empathy that they may otherwise feel. There are ways to fight against “cyberbullying”， but many parents aren’t aware of them-and many bullied kids feel too overwhelmed to deal with the situation.Passage outlineSupporting detailsA general 1. ________◇Kids of all ages are 2. ________ to experience schoolrelated stress.◇School anxiety may happen all year round,3. ________when the new school year begins.4. ________ofschool anxietyTeachersThe school anxiety from a bad experience with a teacher can 5. ________for a long time.FriendsThe problems such as fearing to fall 6. ________friends and being afraid of not having enough friends should be 7. ________ together but not alone.BulliesGood news：·School bullies are being paid more attention to than before.·Help is more easily 8. ________as most schools have antibullying programs and policies.
